Shields for devices and components are made to measure according to the requirements of the customer. The manufacturing takes place on modern laser cutting machines or are stamped. The parts are manufactured individually as single pieces or in series. Depending on the requirements of the parts they can be finally annealed to ensure the maximum shielding integrity.
Shielding for laser transformer:
Shielding for crack test system::
In the course of a routine check of the high voltage inspectors it is noted that magnetic fields are produced at the workplace of the magnetic crack test system. These magnetic fields are above the SUVA limit value of 500µT / 50Hz. If the plant is in operation currents of up to 7'100A flow. The fields should be limited with a shield but the access to the system not affected. Objective: to maintain the SUVA limit value with a large safety factor.
A three-part sliding door system is chosen as solution. When the sliding door is open, access is unhindered. The sliding doors can be pushed in front of each other on both sides. When the sliding doors are closed the SUVA limit value is in perfect compliance. Without shielding: 540µT, with shielding: nearly 40µT.
Shielding for distribution cabins::
The distribution cabin is directly mounted on the outside wall of the building. Inside the building is the workplace of a goldsmith. Magnetic field measurements show values significantly above 1µT. To reduce the fields to values under 1µT the distribution cabin is being shielded on the inside.
Shielding for electronic assemblies::
External fields are disturbing an assembly with several transformers. With the shielding mounted on the outside of the housing, these external fields are reduced to non-critical values. The assembly will then work correctly.
Shielding for magnetic sensor::
External DC magnetic fields disturb the sensors in traffic safety systems. The interference fields can be shielded with the shield housing. The traffic safety system will then work correctly.
